‘Zoolander 2’ is a hot mess (Our grade: D+)

A film cannot live on celebrity cameos alone. But “Zoolander 2” is going to try. Because cameos are low in calories, and “Zoolander 2” hates calories, because they make you fat, and “Zoolander 2” hates fat because it means you’re a terrible person. But not as much as “Zoolander 2” hates male models, who are dumb and useless.

This appears to be the thought process of the sequel to the stupid-funny cult comedy of 2001 that parodied the world of fashion, in all of its petty extravagances and vanities. While the first made endearing dim bulb Derek Zoolander (Ben Stiller) an oft-quoted comedy icon, the too-little, too-late sequel is not so hot right now.
